There is a joke about a love poem written by a mathematician on Valentine's Day. Who can help?

Because its eccentricity is always zero.

What I think of you is a circular decimal,

Over and over again, stubborn.

We are parabola, you are the focus, I am the directrix,

I miss you as much as you miss me.

A zero vector can have many directions, but only one length.

Just like me, I can have many friends, but there is only one you, which deserves my protection.

Life can be sweet or bitter, but it won't be boring without you.

Just like the denominator, it can be positive or negative, but it can't be meaningless and its value is zero.

With you, my world is infinite,

Because there is no real number to express, I love you deeply.

I feel like an exponential function based on the natural logarithm e,

No matter how much wind and rain, true feelings remain the same.

No matter what random variables are in front of us, no matter how big the variance is in the future, I believe that after the trough, will the peak be far behind?

Your life is my field, and your thoughts are my corresponding laws.

Your smile must be a necessary and sufficient condition for my existence here.

If your heart is the X axis, then I am a sine function, rotating, receiving and releasing around you.

If my heart is the X axis, then you are a parabola with an upward opening and a negative δ, which will always be in my heart.

The surprises and hopes I bring you every day,

Just like every element in an infinite set, although inexhaustible, it is different.

If one day we are on both sides of the earth, so far away,

Then I must follow the great circle through the center of the earth to your side, even if I am climbing.

If one day we are separated in a straight line,

Then I must cross the barrier of time and space, draw a common vertical line and run to you, and I don't want to stay for a moment.

But if one day, unfortunately, we are thrown to the two ends of the number axis by God, the positive and negative are infinite, and life and death are broken.

It doesn't matter, as long as the countdown is required, we will be together forever.

How mysterious and wonderful the lover is,

Just like mathematics, it can be so popular, but it is so profound.

Only by mastering the rules of real questions and the examination outline,

In order to knock on the ivory tower and welcome the lover's arms.

I don't know if this is it.
